HOSE-COUPLING;

Application filed June 13, 1918. Serial No. 239,751.

To all whom it may concern: 1 Be it known that I, JAMES J REYNOLDS, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Hose-Couplings, of which the following is a full, clear, and exact description, such as will enable others skilledin the art to which it appertains to make and use the same. v

This invention relates to hose couplings of the kind that are used on railway cars for connecting together the hose extensions on the steam or air pipes of adjacent cars. One object of my invention is to provide a hose coupling of the general character re= ferred to that can be coupled and uncou pled easily and which is so constructed that the coeperating tubular members of same which communicate with the hose exten sions are locked so securely together-thata tight joint between said members 7 is assured. v

' Another object is to provide a practicable hose coupling of simple design whose 00- operating parts are so constructed and arranged that the coupling can be successfully used with short hose extensions owing to the fact that the jaw members and the tubular members of the coupling can be engaged and disengaged by a slight movement longitudinallyof the axis of the coupling.

Other objectsand desirable features of my invention will be hereinafter pointed out. I

Figure 1' of the drawings is a top plan view of a hose coupling constructed in accordance with my invention 7 Fig. 2 is aside'elevational view of said coupling, partly in vertical section; and V Fig. 3 is a perspective view ofone of the jaw members. I

The coupling. briefly, described, consists of two jaw members provided with coijperating interlocking portions, tubular members on said jaw members arranged in longitudinal alinement with each other and communicating with the hose extensions which the coupling connects together and means of novel construction for. drawing said. jaw members into locking engagement witheach other and for forcing said tubular members together so as to. producea tlght joint between the abutting'faces on the innerends of said tubular members,

Referr g. to h r i gs whichii l trate the preferred form of my invention, A de ign te two j we emb rs nd B des gnates two tubular members loosely mounted in said jaw members and adapted to be connected to the hose extensions on adjacent railway cars. Each of the jaw members A consists of a casting that comprises a body portion 1 arranged transversely of the coupling and a side portion 2 arranged longis tudinally of the coupling. The two jaw members of the coupling are adapted to be arranged in the position shown in Fig. 1, namely, with the two body portions 1 spaced apart and with the side portions 2 arranged on opposite sides of the longitudinal axis of the coupling, the side portion 2 on one jaw member projecting forwardly and the side portion of the other jaw member projecting rearwardly. Each jaw member is provided with two jaws 3 and 1 arranged on the body portion 1v and on the outer end of the side portion 2, respectively, as shown in Fig. 3.

When said jaw members are arranged in operative engagement with each other the jaw 4 on the side portion of one member will engage the jaw 3 0n the body portion of the other member, and the jaw 8 on the body portion of the member first referred to will engage the jaw 4 on the side portion of the other member. Thetwo tubular-meme bers B of the coupling are of the same shape and construction and each consistsof atu butlar portion 5 provided at its inner endJwith a head 6 and at its outer end with an externally screw-threaded portion 7. Said tubular shaped members are reciprocatingly jmounted in holes 8 formedin the body portions 1 of the jaw members and he meeting faces of the heads 6 on said tubular members are recessed so as to receive a gasket 9 that forms-a tight joint between the heads 6 on the tubular members B when saidmemb ers are forcedtoward each other. 7

The feature of my improved coupling which I believeto be novel is the meansused for drawing the jaws on thejaw members A into engagement @with each. other and for forcing the headson the tubular members B toward each other. Saidmeans consists of sleeves 10 ,slidingly. mounted onjthe tubular portions 5. of the members B and provided with external screw threads 10 nuts 11d rotatably mounted on said sleeves 'andfjournale d in the ja w me'mbersA; and

plungers 12 reciprocatingly mounted' in the jaw members, A andfarrangedl between the heads 6 on the tubular members and flanges 11)" on the sleeves 10. Thejaw member A of each half or part of the coupling is provided with a pair of arms 13 having transversely-disposed grooves 14; formed in the inner sides of same that receives a flange or annular rib 11 on the nut l1 which cooperates 1 with said jaw member, thereby preventing said nut from moving longitudinally with relation to the jaw member when said nut is rotated on the sleeve with which it cooperates. The sleeves 10 are mounted on the members B in such a manner that they can move freely longitudinally of the coupling, but cannot turn or rotate relatively to the jaw members A. This can be effected in various ways without departing from the spirit of my invention, but I prefer to-provide each of the sleeves 10 with wings or lugs 10 that bear against the arms 13 on the jaw member with which said sleeve cooperates, as shown in Fig, 2.

To connect the two parts orv halves of the coupling together one of the jaw members Ais first moved laterally toward the other jaw member and then moved longitudinally slightly so as to cause the cooperating jaws on saidmembers to engage each other, th-us temporarily connecting the members A and also positioning the tubular members B in longitudinal V alinement with each other. Thereaftenthe nuts 11 are turned So as to move the tubular members B inwardly into engagement with each other and also move the jaw members A outwardly so as to cause the cooperating jaws3 and 4 on same to be drawn into snug engagement with each other; Two-release or vuncouple the coupling it isfonly necessary to turn the nuts 11in the reverse direction so as to relieve the clamp other j aw member.

ing pressure on the aw members and on the tubular members, and thus permit the two parts or halves of the coupling to be separated. The nuts 11 can be provided with lugs 11, so as to facilitate turning said nuts, and. the body portion lof each jaw member can be provided with a laterally-projecting arm 15 arranged in vertical alinement with the jaw 3 on saidvbody portion, as shown in Fig. 3. The a purpose of providing the jaw member witha laterally-projecting arm 15,

arranged above the'jaw 3, is to enable said jaw memberto becoupled to a coupling memberthat is not equipped with jaws fofi the samedesign as-the jaws 3 and 4 herein shown Whenused in the manner above re ferred to,- namely, in conjunction with a coupling member not. provided with eo6peratingjawsthat hold the'two membersinthe same'horizontal. plane, the arm 15 on the j aw memberv of my improved coupling projects laterally over the j aw member on] the other ownwardly relatively to the A coupling of the construction above described insures an absolutely tight joint be- 7 tween the cooperating tubular members B of same, owing to the fact that the heads 6 on said members are forced toward each other by the endwise pressure which the plungers -l2-exertonsaid heads when the nuts 11 are hose extensions, owing to the fact that the jaw'members and tubular members are so constructed and'arrange'd that they 'can be tudinal movement;

Having thusdescribed my invention, what I claim, and desire to secure by Letters Patent, is:

move into intimate interlocking engagement in one. direction. 7 v

2. A hose. coupling, comprising jaw members providedwith cooperating interlocking portions, tubular members reciprocatingly mounted in said jaw members and arranged with eachother when said nutsare turned V in longitudinal alinement 'with each' ther,
